Hi Peeps. and a good afternoon to all :-)
A chap at work who owned a 850 said to me, when I come round to changing my spark plugs I should opt for the multi type with the extra arms thingys on them LoL ( having a blonde moment forgot the name )

i used to use Bosch Super 4's in my cheesewedge & did look for them for the 850, but sure they only listed them for the T-5R. I was new at the time & didn't realise they are the same as the normal T-5 so just brought normal plugs

i have heard of arms falling off the multi-sparkplugs but not sure on all of the details so could of been the wrong grade for the car etc

arms falling off !!!! that sounds expensive !!! :-0

as i say i can't remember the full details so might of been an exempt on a very highly modified car, i ran them fine on my cheesewedge. But no its not a good idea having the spark plugs falling apart lol

i used the bosch super 4's on my old 2.0ltr calibra and within 6 months they had burnt through the ceramic would never try them again

All spark plugs have a heat rating, the number of electrodes however has no relation to it. Most VW's have multi-electrode plugs or 'triple chancers' as we call 'em at wotk !

[Jod T5]

IMO a hype...

Contrary to popular belief you don't get 3 or 4 sparks depending on how many electrodes there are . The spark will always take the easiest path , that is the electrode with the smallest gap .. when this wears the spark will have more difficulty bridging the gap and will choose the next easiest route , one of the unworn electrodes etc etc .. The purpose of multi electrode plugs is long life that's all . These plugs now last 72000 miles on the later Volvo with the "R" engine type plugs ..

There is but one code you need to remember - NGK BKR7EVX

99% of the time they are just the best - and about a fiver per hole!

Even J said so - and that was 4 years ago...

Unfortunately I run my car like a lune - so I have gone up one to the iridium 8's by NGK. Just had a look at mine after 8K, to which said infamous Volvo indie garage owner's chief mechanic (to the stars) aka Tom, said they were the best colour plugs he had seen in his entire life.

Those multi arm jobbies are just a fad.

.

I'd totally agree with that.

[nobananas]

That's whats in mine too ! Don't think they were a fiver each though !

[Wobbly Dave]

That's all I ever paid.

OE everytime.

However I am non-turbo - so there may be a case for the above.

Tis tried tested and trusted for T5 for a long time. (good aliteration eh?).
